Saw this on highend, this is a new CG movie with a hyper realistic CG human character as the show's star. Check it out.

My question is, what's the point to have a realistic CG human in a realist worldwar II setup? I understand they tried to bring Anna Frank back to life, but.... Nothing will ever be better than a real human.... Another tech. masturbation?!
